SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 777,447, dated December 13, 1904.

Application filed October 29, 1904. Serial No. 230,570- (No model.)

To all whom it may concern:

Be it known that I, AXnL A. S'I'ROM, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in SwitclnStands, of which the following is a specification.

The object of my invention is to provide on a railway-switch stand an improved construction of stop device serving to confine the connecting-rod, at the end thereof engaging the switch-stand crank, against displacement at the ends of the throw of the stand, but which end shall be free to be disengaged from and replaced into its connection with the crankin an intermediate position between the ends of said throw.

In the accompanying drawings, Figure 1' shows by a view in elevation a switch-stand equipped with my improvement. Fig. 2 is a section taken at the line '2 on Fig. 1 and Viewed in the direction of the arrow, and Fig. 3 a perspective view of one of the two similar stops.

A is a switch-stand of the construction shown and described in Letters Patent of the United States No. 7 09,614, granted to me September 23, 1902. My improvement is, however, 'applicable to other constructions of switch-stand.

B is the connecting-rod, seating at the apertured head a on one end over the pin 6 of the crank Z) on the lower end of the vertical spindle C, journaled in the stand and adapted to be operated through the medium of a lever or handle D for throwing the switch, (not shown,) with which the opposite end of the rod B is connected. In the position of the crank I) at each end of its throwits pin end with the rodhead (0 upon it comes underneath a stop-bar E, which obstructs the head against rise, and thus prevents its separation from the crank while the rod is performing its switch-holding function, whereas to permit ready removal of the switch-rod, as when broken or otherwise injured and requiring to be removed for repair or replacement by another, it is only necessary to turn the spindle C to bring its crank between the stops, where the rod-head is free to be lifted off the crank.

Each of the two stops required for my purpose is preferably formed of a wrought-metal bar (iron or steel) in the shape illustrated, which resembles that of the letter 2, wherein the part 0 forms the foot, apertured to re ceive a rivet (Z, the part c the neck, and the part a the head or stop proper. This form of stop is advantageous in the way of ease and cheapness of manufacture and that of facility of application, requiring only a single rivethole and a single rivet to be provided for securing the stop-bar through its foot portion to the stand-base A, and adapting the stopbar to hear at its outer edge against the adjacent leg A or side of the switch-stand, where by its stability is increased and the employ ment of the single fastening-rivet rendered. adequate for security.

What I claim as new, and by Letters Patent, is

1. In combination with a switch-stand, a stop-bar on each side of the rotary spindle, fastened to the stand and projecting over the plane in which the spindle-crank and switchrod head thereon move, to obstruct said head against rise at the ends of the throw of the crank, substantially as described.

2. In combination with a switch-stand, stopbars secured to and rising from the base of the stand at opposite sides of the rotary spindle and projecting over the plane in which the spindle-crank and switch-rod head thereon move, to obstruct said head against rise at the ends of the throw of the crank, substantially as described.

3. In combination with a switch-stand, stopbars secured to the base of the stand one at each side of the rotary spindle and bearing at its outer edge against the adjacent switchstand side, said stop-bars rising from said base and projecting over the plane in which the spindle-crank and switch-rod head thereon move, to obstruct said head against rise at the ends of the throw of the crank, substantially as described.

4:. In combination with a switch stand,
